      Hello i am still trying to make JPA work with simple maven archetype for WELD on servlet containers. I added seam-solder and seam-persistence modules (both cr 04).
      So my pom dependecies look like this:



      <dependency>
               <groupId>org.jboss.seam.persistence</groupId>
               <artifactId>seam-persistence</artifactId>
               <version>${seam.solder.version}</version>

     </dependencies>



      I also added persistence.xml with the following entries:



      <?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0">
    <persistence-unit name="foo" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
            <properties>
                <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect" />
                <property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver" />
                <property name="hibernate.connection.username" value="sa" />
                <property name="hibernate.connection.password" value="" />
                <property name="hibernate.connection.url" value="jdbc:hsqldb:mem:todo" />
                <property name="hibernate.hbm2ddl.auto" value="create" />
            </properties>
        </persistence-unit>
</persistence>



      My bean xml looks like this:



      <beans xmlns="http://java.sun.com/xml/ns/javaee"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:s="urn:java:ee" 
   xmlns:t="urn:java:org.jboss.seam.persistence.transaction"
   xsi:schemaLocation="
      http://java.sun.com/xml/ns/javaee 
      http://docs.jboss.org/cdi/beans_1_0.xsd">

      <t:SeSynchronizations>
         <s:modifies/>
      </t:SeSynchronizations>

      <t:EntityTransaction>
         <s:modifies />         
      </t:EntityTransaction>
</beans>



      i have a class that has



      public class EmProducer {
     
     @ExtensionManaged
     @Produces
     @PersistenceUnit
     @ConversationScoped
     EntityManagerFactory producerField;
}



      But i cannot inject entity manager anywhere.


      I tried obtaining it via 


      Persistence.createEntityManagerFactory("foo")



      But i always get an exception:




       javax.persistence.PersistenceException: No Persistence provider for EntityManager named foo



      It is a strage because i named my persistance unit in persistance xml foo.
      Any help would be appreciated.


      Thanks in advance.
